therapy and cannonist

[Mr. Fix it]

so i have canonist in play under my control. i have a cabal therapy in the yard.
I cast brainstorm and this uses up my only 1 nonartifact spell for the turn. does the canonist ability prevent me from being able to flash back therapy in the same turn as i would be killing the canonist to pay the flashback?

Oracle text: Each player who has cast a nonartifact spell this turn can't cast additional nonartifact spells.

Yes, it does.

[Anusien]

No you cannot flashback the Therapy. You actually start to cast the spell long before you would pay costs. This is different from sacrificing things that would trigger, like Tinkering away a Chalice of the Void.

To be more specific:

You choose modes and targets before you pay costs for casting a spell. Since you cannot cast the spell, you cannot announce modes and targets, thus you cannot pay its cost.
